  By the way, when installing the hot water supply device, it is necessary to store various settings indispensable for the hot water supply device to operate. In addition, if the hot water supply apparatus is operated immediately after installation, the air layer accumulated in the piping has caused problems such as prolonged operation time and markedly deteriorated heating efficiency. Therefore, it is necessary to check the operation performance of the hot water supply device by always venting the air before the operation and performing a boiling test operation on the air.

  Usually, the installation of hot water supply equipment is performed by workers such as electrical contractors and construction contractors, but there are cases where multiple workers are replaced and are in charge of the installation, which is indispensable before the operation of the hot water supply equipment. It is easy to forget various settings, air venting, and trial operation.

  As a result, the user suffers damage such as slow operation time of the hot water supply device, poor heating efficiency and running out of hot water in the hot water storage tank after a while.

  In order to solve the above-described conventional problems, the remote controller for a hot water supply apparatus of the present invention changes the input status of operation setting items stored in the storage unit when it is determined that the hot water supply operation of the hot water supply apparatus is normal. For confirmation work that requires a long time, such as air evacuation work in a pipe or boiling test operation, even if the storage unit is not input at the first power-on, the next power supply There is no need to input again at the time of startup, and unnecessary input is not required. In addition, for users who have little knowledge about the remote controller for a hot water supply device, the fact that a message that should be displayed to the installation worker at the stage of installation is displayed at the time of use is rather anxious. .

  The remote controller for a hot water supply apparatus of the present invention does not need to input again when the power is turned on next time even if it is an operation setting item that has not been input when the power is first turned on.

A first aspect of the present invention is a panel unit that displays operation setting items when power is first turned on after the installation of a hot water supply device, an operation unit that inputs operation setting items displayed on the panel unit, and input of the operation setting items. A storage unit for storing the situation, and before supplying all the operation setting items, the power supply is
When the power is turned off, the remote controller for the hot water supply device that displays the non-input items of the operation setting items again on the panel section when the power is supplied next time. Or by specially operating the operation unit without providing the input skip switch, thereby skipping the input of the operation setting item and ending the test operation without inputting the operation setting item, and then boiling the operation normally An operation state determination means for determining whether the operation is performed is provided, and when the normal boiling operation is performed with no operation setting item being input, the operation state determination means normally performs the boiling operation. If it is determined that the operation setting item has not been input, the remote controller for the hot water supply apparatus is set to have already been input .

  As a result, even if the operation setting item has not been input when the power is first turned on, it is not necessary to input again at the next power-on, and it is possible to save the trouble of making an extra input.

  In particular, in the second invention, the operation state determination means in the first invention determines normality of the hot water supply operation based on the amount of hot water heated up within a predetermined time, and in a short time of several minutes or tens of minutes. Therefore, it can be confirmed that the boiling operation of the hot water supply apparatus can be normally operated.

  According to a third aspect of the invention, in particular, in the first aspect of the invention, the operating state determination means detects the operation of the boiling circulation pump, and if the temperature detected by the boiling pipe temperature sensor is equal to or higher than a predetermined temperature in a certain period, The normality of the hot water supply operation is determined, and it can be confirmed that the boiling operation of the hot water supply device can be normally operated in a short time of several minutes or tens of minutes.

  In particular, in any one of the first to third inventions, the fourth invention is to prevent the hot water supply device from being heated during input by the operation unit, and before performing the boiling test operation. It is possible to prevent in advance a failure of the hot water supply apparatus that occurs due to the boiling operation being performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows an external view of a remote controller for a hot water supply apparatus according to the first embodiment of the present invention, and FIG. 2 shows a configuration diagram of the remote controller for a hot water supply apparatus.

  As shown in FIG. 1, a remote controller 101 for a hot water supply device includes a panel unit 102 that displays a boiling temperature setting value, time, amount of hot water in a bathtub, and the like, and a menu switch that calls a setting screen when setting the time or setting the remote control itself. 103, a selection switch 104 for selecting a specific setting confirmation item from the options displayed on the panel unit 102, and a confirmation switch 105 for confirming the setting confirmation item selected by the selection switch 104.

  In addition, as shown in FIG. 2, the remote controller for hot water supply apparatus 101 includes a control unit 201 that controls display contents of the panel unit 102, information for displaying on the panel unit 102, set values and time of the hot water supply device, and the like. A storage unit 202 for storing and an input unit 203 for inputting a set value of the hot water supply device are provided. Note that the input unit 203 includes a selection switch 104 and a confirmation switch 105.

The set value of the hot water supply device stored in the storage unit 202 can be illustrated as shown in FIG. 3, for example. According to FIG. 3, the setting confirmation item 301 is a confirmation item “whether the hot water storage tank is full at the time of installation”, and it is indicated that the setting confirmation item has been input. Further, the setting confirmation item 302 is a confirmation item “whether or not to perform air venting”, and indicates that the setting confirmation item is not input. The setting confirmation item 303 is a setting item of “setting of electric power charge system”, and indicates that the setting confirmation item has been input. Further, the setting confirmation item 304 is a confirmation item “whether or not to perform the boiling trial run”, and indicates that the setting confirmation item has been input.

  The operation and action of the hot water supply remote controller 101 configured as described above will be described below.

  First, when the power is turned on for the first time after an operator installs the hot water supply device, the power is also supplied to the hot water supply remote controller 101. At this time, the control unit 201 first confirms the contents of the storage unit 202. When the power is turned on for the first time, all the setting confirmation values of the hot water supply device stored in the storage unit 202 are not input. Therefore, when the power is first turned on, the control unit 201 displays the setting confirmation items that have not been input on the panel unit 102 so as to be included in the setting selection screen 501 as shown in FIG.

  In FIG. 4, in the setting selection screen 501, the setting confirmation item 302 “whether to perform air venting”, the setting confirmation item 303 “setting of the electric power charge system”, and the setting confirmation item 304 “execute boiling test run” are performed. The operator confirms and inputs each message. The flow of input will be described in detail. For example, when the operator desires to perform air bleeding in response to the message “whether to perform air bleeding” of the setting confirmation item 302, the operator presses the confirmation switch 105. Then, the pump of the hot water supply device is activated and the air in the pipe is extracted. When the air venting operation is completed, other setting confirmation items stored in the storage unit 202 are displayed. Thereafter, a message “whether or not to perform the boiling test run” of the setting confirmation item 304 is displayed. If the setting confirmation item is not always displayed after the setting confirmation item “whether or not to perform air venting”, the boiling operation is performed before the air is vented. It is displayed for all setting confirmation items and continues until the input is completed.

  When the input is completed and the setting selection screen 501 is no longer displayed from the panel unit 102, the worker (or the user) can perform the boiling operation from that point. That is, while the setting selection screen 501 is displayed and the operator confirms and inputs the setting confirmation item, a request for the heating operation is not accepted. Therefore, the boiling operation is not performed before the operator (or the user) vents the air, and the malfunction or malfunction of the hot water supply apparatus can be suppressed.

  In this way, the setting contents of the setting confirmation items are displayed on the panel unit 102 for the operator at the time of installation, so that the user can be alerted, and the setting and necessary work can be performed without forgetting, so that the failure of the hot water supply device can be performed in advance. Can be suppressed.

  However, assuming that a power failure or the like occurs during setting and the power is not supplied, not all setting confirmation items are always input. In addition, it takes 10 to 30 minutes for the air venting work. If it is unavoidable that the work time is unavoidable, the setting is skipped as no entry, and other setting confirmation items are entered first to finish the input work. can do.

  Therefore, in order to prevent the possibility of the operator forgetting to input items that have not been input, the control unit 201 displays only the setting confirmation items that have not been input in the setting selection screen 501 when the hot water supply remote controller 101 is activated next time. It is displayed on the panel unit 102 so as to include it.

As described above, the uninput items are displayed again when the power is turned on, so that the operator can surely input without forgetting. In addition, when the air venting operation and the boiling trial operation, which are particularly important operations, are not performed, the user is prompted again to suppress the failure of the water heater.

  It should be noted that an input skip switch may be designed in the hot water supply remote controller 101 so that the operator can arbitrarily enter the setting confirmation item. Further, it may be possible to carry out by a special operation such as continuously pressing the confirmation switch 105 for several seconds without providing a switch.

(Embodiment 2)
In the first embodiment, setting confirmation items that are not input when the power is first turned on are displayed again when the power is turned on next time, so that the operator can input without fail. However, if for some reason, the user does not perform air venting or boiling test when the power is first turned on, and each setting check item is not entered, but the user can perform boiling operation after that, the air venting work is performed thereafter. There is no need to perform a boiling test run.

  Therefore, as shown in FIG. 5, a remote controller 101 for hot water supply apparatus is configured. The operation state determination means 502 detects whether the hot water supply operation of the hot water supply device is operating normally. Specifically, the operation state determination means 502 makes a determination based on the circulation pump and the raising temperature of the hot water supply apparatus.

  Here, in order to describe the operation state determination means 502, the configuration of the hot water supply apparatus will be described in detail with reference to FIG. The hot water supply apparatus shown in FIG. 6 includes a heat pump unit 602, a hot water storage unit 603, and a heating unit 604.

  The heat pump unit 602 includes a compressor 605, a water / refrigerant heat exchanger 606, an expansion valve 607, and an evaporator 608, and the refrigerant circulates in the heat pump unit 602. Carbon dioxide refrigerant is used as the refrigerant.

  A hot water storage tank 609 and a water heat exchanger 610 are incorporated in the hot water storage unit 603. Further, the heating unit 604 is provided with a heat radiating means 611 and warms the floor by the heat radiated from the heat radiating means 611. In addition, even if it is other than floor heating as mentioned above, the form which can be utilized for bathroom drying, bath cooking, etc. may be sufficient, for example.

  When heating the hot water in the hot water storage tank 609, it is supplied to the water refrigerant heat exchanger 606 from the boiling forward pipe installed at the lower part of the hot water storage tank 609 to the water refrigerant heat exchanger 606 while activating the water circulation heat pump 612. The hot water heated via the vessel 606 is returned to the upper part of the hot water storage tank 609 through the boiling return pipe 611. This boiling operation is performed until the hot water storage tank 609 is filled with hot hot water by the temperature sensor 614 (614a, 614b, 614c). The heated hot water temperature is detected by a boiling pipe temperature sensor 613, and the number of rotations of the boiling circulation pump 612 is controlled so as to keep the value constant.

  In addition, when the floor heating operation is activated, the water is supplied from the primary forward pipe 612 provided in the upper part of the hot water storage tank 609 to the water heat exchanger 610, and the inside of the heating unit 604 is passed through the water heat exchanger 610. Transmit heat to circulating hot water. Hot water in the heating unit 604 heated by the water heat exchanger 610 flows to the heat radiating means 611 via the secondary return pipe 613 and is radiated from the heat radiating means 611. The radiated hot and cold water is heated again by the water heat exchanger 610 through the secondary forward pipe 614.

  Further, the hot water on the hot water storage unit 603 side radiated by the water heat exchanger 610 is returned to the lower part of the hot water storage tank 609 through the primary return pipe 615.

In such a hot water supply apparatus, the operation state determination means 502 is such that the boiling circulation pump 612 is operating and the temperature detected by the boiling pipe temperature sensor 613 is kept at a high temperature (for example, 80 degrees or more) for a predetermined time. Then, it is determined that the hot water supply operation of the hot water supply device is operating normally.

  In addition, the operation state determination means 502 may determine using the temperature sensor 614 (614a, 614b, 614c) other than the above method. For example, when the temperature sensor 614a detects a high temperature (for example, 80 degrees or more) and the other temperature sensors 614b and 614c detect a low sound (for example, 20 degrees), a predetermined time after starting the boiling operation When the temperature sensor 614b detects a high temperature (for example, 80 degrees or more), it is determined that the hot water supply operation of the hot water supply device is operating normally.

  As described above, when the operation state determination unit 502 determines that the hot water supply operation is normal for the setting confirmation item that is not input when the power is first turned on, the control unit 201 sets the “air removal” of the setting confirmation item 302 stored in the storage unit. And the setting confirmation item 304 “whether or not to perform the boiling test run” are set as input, and the storage content is changed.

  Therefore, setting confirmation items that are not input when the power is first turned on are not displayed again when the power is turned on next time, and it is not necessary to perform extra input. In addition, for users who have little knowledge about the remote controller for a hot water supply device, the fact that a message that should be displayed to the installation worker at the stage of installation is displayed at the time of use is rather anxious. However, there is no such anxiety.

  In this embodiment, the description has been made on the assumption that the air venting operation and the boiling trial operation are not input, but the operation state determination unit 502 also performs the hot water supply operation for setting confirmation items other than the air venting operation and the boiling trial operation. When determining the normality, the control unit 201 may change the input status of the storage unit.

  As described above, the remote controller for a hot water supply apparatus according to the present invention can be applied as a remote controller for an electric hot water supply apparatus and a gas hot water supply apparatus in addition to a heat pump hot water supply apparatus.
